Green energy transportation system and energy transportation method

This invention describes a system to transport renewable energy by converting it into methane. It starts by using renewable electricity to make hydrogen, then combines that hydrogen with recycled CO2 to synthesize methane. This methane is then transported to where energy is needed, burned to generate electricity, and the CO2 produced is captured and sent back to the methane synthesis site, creating a closed loop.

Why it matters: The fundamental challenge of energy losses across multiple conversion steps and the high cost of industrial-scale carbon capture and CO2 transport remain significant, with no major technological shifts in the last two years to overcome these economic hurdles.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedIndustrial chemical reactors, carbon capture, pipelines.
